The Third type of Bad Dialogue is Cartoonishly Evil Dialogue.
The only other toon person aside from maybe Cruella or Jafar (strictly classic cartoons) that should get a pass for this Cartoonishly Evil Dialogue of theirs is The Judge from Who Framed Roger Rabbit all of those were done intentionally to be seen as Cartoonishly Evil because the movies were using a good chunk of comedy alongside the cheesy dialogue rantings within.
1st problem villains say Cheesy things, discuss silly plans, and maybe label themselves directly out loud as evil.
2nd issue makes a villain look incredibly shallow and brainless and absolutely unrealistic.
3rd point it comes as Darn unnatural for most villains of any story to act this way.
4th point often lacks subtext.
Number 1 thing your villain should not see themselves as evil! That's the big problem, I have with Descendants Wicked World concerning Mal's character with the excessiveness lengths that CJ or Zevon go to keep reminding us Mal's suppose to evil and the "I'm Evil" song is not that cool either . Yes I said it's a stupid song on a large scale sung by Mal that she should never had to even recorded honestly, Skylights.
A villain should believe they are the hero of their story alone.
4th type of Bad Dialogue of Round 3 is a jarring change of subjects.

And 5th Bad type of Bad Dialogue is Rushed Emotional Reactions explained below.
"'Strong emotions'" the video guy emphasizes as he brings the last point that makes it poor dialogue. "'NEED Time to develop.'"
